The import of pipe is connected, and the outlet of outlet pipe is connected to sewage network, and the electrode connects to the control circuit.This filtrate processing
Device is by the thick, setting of fine filtrator and the electrolysis of electrode, the organic pollutant removal in percolate.
Although above-mentioned technical proposal solves the drawbacks of conventional solution, can not make only by simple electrolysis
Filtrate meets in China " household refuse landfill sites pollutant catabolic gene standard " (GB16889-2008) promulgated in 2008 to filtrate
The requirement of middle total nitrogen, therefore this leachate treatment technology in the prior art is no longer satisfied discharge standard requirement.
And at the same time notification number be CN104445641A prior art discloses a kind of for the compound micro- of water process
Biological slow-released and preparation method thereof, this method carries out processing to water body using complex microorganism and meets China's water process mark
To the requirement of total nitrogen content in standard, but the following is needed to pay attention to when carrying out water process using microorganism:
(1) same substrate competition reaches ideal processing target in the residence time limited for each part in pond,
Sludge retention time (SRT) must be made to maintain suitable level, to guarantee microorganism energy mixed growth；(2) in order to guarantee
Higher sludge concentration needs biggish regurgitant volume, causes the denitrifying anoxia condition of second level to lose, needs to add further amounts of
For carbon source to consume extra dissolved oxygen, this increases the operating cost of operating system again.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is requiring in appropriate means, compact-sized, occupied area is small, is convenient for
It operates outside these advantages, releases the percolate processing side generated in a kind of Disposal of Domestic for meeting national water process standard
